I also know how you feel. I'm getting married the day as you and I just went out Tuesday and bought a new dress. I had been doubting my dress since I bought is in January because it just wasn't "me". The new dress i bought I absolutely love, its the prefect choice for me. So you really need to go with how you feel if you know you aren't attached to the first one then get a new one. You have just enough time. My dress is coming in 2 weeks before we leave for Mexico. Good thing it only needs to be shortened haha. But either way your dress does look great on you! Just go with your gut!
